电力系统主动解列仿真平台的研究

解列是电力系统在受到大的干扰,系统完整性无法保持的情况下将系统分解成几个孤岛的控制。作为一个复杂的综合决策问题,对电力系统解列控制的研究还很不充分。为了深入完整地研究解列控制,该文专门构建了一个仿真平台。该平台能够对解列控制的各个过程进行仿真,同时对各过程的决策算法保留了较好的兼容性。对IEEE-68节点系统的仿真证明了该仿真平台的有效性。仿真结果揭示了一些新的现象,同时为下一步的研究指明了方向。

Studies on the Integrated Simulation Platform Designed for Active Splitting Control of Power Systems

Power system splitting (also called as system islanding) is to split the interconnected power grid into several islands when the system is subject to severe disturbances and system integrity can not be hold, so that the continuity of power service on the islands can be sustained. As a complex decision problem, the studies on splitting control are far below adequacy. In order to probe into splitting control more concretely and thoroughly, a simulation platform that integrates all necessary modules aiming at different procedures in a splitting process is introduced in this paper. The platform can not only simulate the entire physical process of system islanding but also possesses good compatibility to various approaches for further studies. Simulations on IEEE 68-system demonstrate the validity of the platform. Many scenarios that have not been expected before have been revealed. Future research directions are pointed out based on the simulation results.
